"Notching" levers to stop complete break.

After seeing a notch on the pazzo levers:
viewtopic.php?f=17&t=24282&start=60
I remember Glen saying it's a dirt bike trick to stop the whole lever snapping off in a fall.
Of course I'm not planning on anyMORE low-speed "whoooopsie doooos"
but I'll plan for it so I can get home, just like wearing gear.
Opinions on doing this?
If to notch, how to notch? With a file? Dremel?
Mine are both replacement levers, that bright silver material which in my experience seems reasonalbly brittle.
Thanks in advance.
